Does anyone use this?....I'll test it out...

I was wondering this...there is basically no way that I can read all of the suggested books in preparation for the test.  I might could have if I had not procrastinated in getting serious about it and signing up.  I will be able to read the great study guide that appears to have all of the main, important things packed into it.  I know that there is no guarantee that this alone will help you pass the test....but I would like to know if the majority of the questions come from materials that are contained in the study guide.  I'd feel better knowing that.  :)
